VFXGen — Stylized VFX Texture Editor

Make stylized particle textures and flipbooks right inside Unity.

Slashes, impact bursts, rune circles, lightning, fire loops. VFXGen is a node-based editor for the textures cartoon effects are made of. Pick a recipe, tweak it, and export a PNG or sprite sheet into your project with the import settings already right, ready for the Particle System's Texture Sheet Animation.

Why VFX artists use it

• Editable recipes, not fixed art. Change shapes, colours and timing, and save your own variations.
• Flipbooks without drawing every frame. Draw a few key poses and VFXGen fills in the frames between them.
• Ready on export. Textures and sprite sheets land in your project already set up correctly.
• Yours to use. Every texture you make is yours to use commercially, with no attribution or royalty. No AI image generation; everything is procedural.

What's included

• 97 editable recipes (86 effects + 11 step-by-step studies) and 51 nodes
• A demo scene: four effects exported from the recipes, playing on particle systems (Built-in and URP)
• Optional URP effects pack (separate download): five ready-made particle effect prefabs plus a demo scene
• Interface in English, Japanese, Korean, Traditional and Simplified Chinese
